2023 Chevrolet Corvette Z06 Redline confirmed: 8,600 rpm
The attached video further confirms the central four-tip exhaust that we saw on the test mules, wider front and rear fenders, a new design for the wheels, a new design for the rear spoiler, as well as the Z06 in convertible form. There are even pictures of the interior, with the audio brand Bose, the so-called “Great wall of buttons” and the slightly square frill.
Based on photos and spy reports, the Z06 will adopt a familiar dual-clutch transmission with small twists. On the one hand, there is photographic evidence of a magnesium casing. Second, the Tremec supplied gearbox handles up to 7,500 rpm in the small block Stingray.
Based on the LT5.5 engine from the C8.R endurance racer, the Z06’s LT6 is expected to displace 5.5 liters and produce over 600 horsepower. Torque is also guessable, but nonetheless, you can expect more than Ford’s rating for the Voodoo. As a quick reminder, the Shelby GT350’s 5.2-liter engine develops 429 lb-ft (or 583 Nm) at 4,750 rpm.
Much like the ‘Vette hybrid which should carry the E-Ray moniker, the Z06 is rounded out with a set of faster massive tires. Specifically, the larger steamrollers photographed on prototypes measure 275/30 by 20 inches at the front and 345/25 by 21 inches at the rear. The most aggressive compound and tread comes from Michelin in the form of the Pilot Sport Cup 2 R, a DOT approved performance tire with an asymmetric pattern and a few side notches.
